Referring to fig. 7, the area of the liquid baffle 803 is sequentially reduced from the near water end to the far water end of the main water pipe 1, the near water end is the end close to the water tank, the far water end is the end far away from the water tank, and the water pressure in the main water pipe 1 is gradually reduced from the near water end to the far water end of the main water pipe 1, so that the amount of water entering the inner branch pipe 301 at the near water end is large, while the amount of water at the far water end is small, and by setting the liquid baffle 803 at the near water end to have a larger area, the liquid baffle 803 is located at the front side of the inner branch pipe 301, so that the liquid baffle 803 can block water flow, reduce the water flow entering the inner branch pipe 301, and block more water flows when the area of the liquid baffle 803 is larger, thereby balancing the amount of water entering the inner branch pipe 301 at the near water end and the far water end, and the specific area of the liquid baffle 803 can be obtained through experiments.
In addition, because the inner diameter of the side branch pipe 3 is smaller, substances in the nutrient solution are easy to precipitate in the inner wall of the side branch pipe 3 when the nutrient solution is conveyed, so that the side branch pipe 3 is blocked, in the application, the rotary baffle plate 302 can scrape precipitated crystals on the inner wall of the side branch pipe 3 through the rotation of the inner branch pipe 301, and in the rotating process of the inner branch pipe 301, the precipitation of the crystals on the inner wall of the inner branch pipe 301 can be reduced under the action of centrifugal force, so that the problem that the precipitates in the side branch pipe 3 are easy to block is solved; in addition, this application can realize the rotation of inner branch pipe 301 through trampling footboard 601 under the state that the start lasts, realizes then that the purpose of scraping off of offside branch pipe 3 inner wall and the getting rid of crystal of inner branch pipe 301 inner wall. In the present application, it is only provided that the pedal 601 can be manually driven by manually stepping on, but the stepping on the pedal 601 can also be mechanically realized, for example, a cam disc and a pressing rod capable of pressing the pedal 601 are arranged on the pedal 601, similar to a sliding plug rod in an engine, so as to realize mechanical automatic intermittent pressing on the pedal 601.
The using method of the invention is as follows:
1. embedding a main water pipe 1, a fixed bottom pipe 2 and a side branch pipe 3 under the ground, wherein the fixed bottom pipe 2 is perpendicular to the ground, the top end of an installation box body 4 protrudes out of the ground, liquid in the water tank enters an inner branch pipe 301 through the main water pipe 1, flows into a sub-cavity between the inner branch pipe 301 and the side branch pipe 3 through an inner pipe liquid outlet hole 303, and finally flows into the ground through a side pipe liquid outlet hole 304; meanwhile, the liquid in the main water pipe 1 enters the movable bottom pipe 5 through the elastic hose 503 and flows into the ground through the inner liquid outlet hole 501 and the outer liquid outlet hole 201;
2. in a starting state, the pedal 601 is stepped, the pedal 601 drives the screw 604 to move downwards along the inner wall of the fixed ring body 602, the screw 604 rotates to drive the main rotating rod 603 to rotate, the rotating force is transmitted to the secondary rotating rod 801 through the bevel gear set 7, the conversion box 802 moves towards the inner branch pipe 301 due to the pressure of liquid, the secondary rotating rod 801 is in staggered contact with the cross plate 805 of the conversion box 802, the rotating force is transmitted to the inner branch pipe 301 through the conversion box 802, the liquid baffle plate 803 and the support rod member 804, so that sediment on the inner wall of the side branch pipe 3 is scraped through the rotation of the inner branch pipe 301, the sediment on the inner wall of the inner branch pipe 301 is thrown away by using centrifugal force, and the sediment is less prone to sediment and better flows out of the pipeline along with water flow by using the impact of water flow when the starting; and when the switching box 802 approaches the inner branch pipe 301, the inclined slide rod 8021 moves along the inclined chute 8011 to the bottom end of the inclined chute 8011, so that the inner branch pipe 301 rotates 90 degrees relative to the side branch pipe 3; at the moment of shutdown, because the liquid baffle 803 loses the pressure of water flow, the conversion box 802 moves reversely, at this moment, the inclined slide rod 8021 moves reversely along the inclined chute 8011, the inner branch pipe 301 rotates reversely by 90 degrees to restore to the original position relative to the side branch pipe 3, so that the sub-cavity including the inner pipe liquid outlet 303 is staggered with the side pipe liquid outlet 304, the suck-back force of the pipeline is blocked by the rotary baffle 302, the side pipe liquid outlet 304 cannot generate serious suck-back condition, and the blockage of the side pipe liquid outlet 304 is avoided;
3. along with the growth of nursery stock, the root system extends to the below ground gradually, needs to remove bottom tube 5 downstream, upwards stretches telescopic link 507 from the recess in footboard 601, then promotes telescopic link 507 downwards to promote to remove bottom tube 5 downstream, guarantee interior liquid outlet 501 and go out liquid hole 201 and align under the effect of latch 5041 and draw-in groove 5053 joint, can realize the removal to removing bottom tube 5.
